Abstract Aim: This study aimed to comprehensively assess the biocompatibility and toxicity profiles of poly(methyl methacrylate) (PMMA) its monomeric unit, methyl methacrylate (MMA), crucial components in dental materials for interim prosthetic restorations. Methodology: Molecular docking was employed predict binding affinities, energetics, steric features MMA PMMA with selected receptors involved bone metabolism tissue development, including RANKL, Fibronectin, BMP9, NOTCH2, other related receptors. The HADDOCK standalone version utilized calculations, employing a Lamarckian genetic algorithm explore conformational space ligand-receptor interactions. Furthermore, molecular dynamics (MD) simulations over 100 nanoseconds were conducted using GROMACS package evaluate dynamic actions structural stability. LigandScout pharmacophore modeling, which employs shape-based screening approach identify potential ligand sites on protein targets. Results: studies elucidated promising interactions between key biomolecular targets relevant applications. MD simulation results provided strong evidence supporting stability complexes time. Pharmacophore modeling highlighted significance carbonyl hydroxyl groups as pharmacophoric features, indicating compounds favorable profiles. Conclusion: underscores applications, emphasizing stability, interactions, safety considerations.
